Question

what is pascle's law ?

Answer 1

hey !!!!!

_________

Pascal’s law states that : If pressure in a liquid is changed at a particular point, the change is transmitted to the entire liquid without being diminished in magnitude.

If F is the magnitude of the normal force on the piston and A is the surface area of a piston, then the pressure, P, of the fluid at the level to which the device has been submerged as the ratio of the force to area.

P = F/A

Since the pressure is force per unit area, it has units of N/m2 in the SI system.
Another name for the SI unit of pressure is Pascal (Pa)

!Pa = N/m2


here we are showing the working of hydraulic brakes Let A1  be the larger area and A2 be the smaller area. As pressure will be same according to Pascal, force while applying brakes will be small:

F1/A1 = F2/A2

Answer 2

Pascal's principle : Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container. A common application of this is a hydraulic lift used to raise a car off the ground so it can be repaired at a garage.

In simple word we can say that Pascal's law basically states that any pressure applied to a fluid inside a closed system will transmit that pressure equally in all directions throughout the fluid. This law is the basic principle that causes hydraulic power in heavy construction machines to work.
